Audio Bhan 6x9 making engine noise help
 

I bought AudioBhan 6x9's a couple of years ago and just recently started hearing loud engine noise.

Any ideas of the cause and solution for this problem. Im totally new to car stereo's so please leave the insults out the door.

Start by checking the ground on your amp.

You need to provide a little more info about your setup. Did you use an amp wiring kit? I'd suggest you follow SS's suggestion by checking the amp ground, if that fails go through the Big 3, that should solve your issue
